GYRUS L. BUOKWALTER, OF LOUDONVILLE, OHIO.

AUDIPHONE Application filed February 13, 1908.

To all whom it may concern.'

Be it known that I, OYRUs L. BUoKwAL- TER, a citizen ol the United States, residing at Iioudonville, in the county of Ashland and State of Ohio, have invented certain new and useful Improvements in Audiphones; and I do declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to audiphones, dentiphones or the like, and the object of the invention is to materially increase the vibration, and by increasing the tension upon the diaphragm and transmitting the amplified vibrations produced thereby to intensify the action on the mouth bit or piece.

A further object ofthe invention is to provide a device of this character which may be conveniently transported from place to place and which may also be locked in openposition by the supporting` handle of the device.

lith these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims.

In the drawings: Figure -1 is a side elevation of the device, Fig. 2 is a longitudinal section, Fig. 3 is a transverse section onv the line 3 3 of Fig. 2, Fig. 4 is a detail perspective view of the diaphragm, and Fig. 5 is a sectional perspective view oi the clamp and its associated handle.

Referring more especially to the drawings, 1 2 and 3 represent respectively telescoping sections, which are arranged to collapse so that the device may be carried in the pocket of a deaf person. The section 1 is supplied at its outer end with thickened shell Ll, into which is bored the holes 5 for the reception of a plurality of spiral springs 6, upon which the pins 7 of the diaphragm 8 are adapted to rest. These springs are adapted to act in opposition to a spiral spring 9, which is secured at one end to an eye 10 carried upon a headed block 10a, which passes through the diaphragm and has a coil spring 10b surrounding its shank between the diaphragm and the headed end to permit of a resilient connection between the two. The spring 9 is connected at its opposite end to the mou th piece or articulator 11 by an eye 12.

r1`he sections 2 and 3 are held distended in l Specification of Letters Patent.

any suitable spring like manner, but I preferably use a spring latch carried by the section 2 and adapted to engage an aperture in the section 3.

The sections 1 and 2 are preferably held apart by a device which is controlled by the Secured to the section 1 is a spring 13 having a right angular end 14 passing through an aperture 15, formed in the outer section 1 and adapted to engage an aperture 16, formed upon the inner end of the casing 2. The inherent resiliency of the spring 13 normally holds its angular end 1 4 out ol" engagement with the aperture 16, and in order that it may be .held in engagement therewith I surround the section 1 with a spring clip 17, which is provided with a pair of ears extending tangentially therefrom to receive the supporting handle 18. This handle is eccentrically pivoted to the eais, and is provided with a cam tace 19, adapted to pass through an aperture 20, formed in the Aspring clip so as to engage the upper side ot' the spring 15 and force its angular extension 141 into engagement with the aperture 16 in the inner section 2. When the handle is lowered the spring retracts its locking end so that the sections are allowed to collapse under the influence of the spring 9.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation. 4 Various changes in the lorm, proportion and the minor details oi construction may be resorted to without departing Vfrom the principle or sacrificing any of the advantages of this invention as defined in the appended claims.

Ihat I claim and desire to secure by Letters Patent is 1. In an audiphone, a mouth piece, a diaphragm therefor, of a plurality of tclescoping sections connecting the same, and an intensiiier connected to the diaphragm and mouth piece which comprises a retractile member for the sections.

2. An audiphone comprising a plurality of telescoping sections, a diaphragm secured to one of said sections, a mouthpiece secured to another of said sections, an intensilier connected with the diaphragm and the mouth piece which comprises a spiral retractile spring adapted to normally hold the sections collapsed or telescoped, a handle on one of the sections7 and means operated by the hanl sections to hold it in extended position, a die for holding the sections in extended posispring operating handle carried by the tion. spring clip and adapted to operate the catch.

3. In an audiphone, a roller, a plurality of In testimony whereof I have hereunto set 15 telescoping sections, a mouth piece carried my hand in presence of tWo subscribing Witby one of said sections, a diaphragm carried nesses.
